I'm starting to understand how to modify the Spica system... I wanted to see how firmwares were distributed and got to the point of the "RFS" file.
Googling around I saw this:
http://movitool.ntd.homelinux.org/tr.../wiki/MoviTool
a tool to read RFS (0.0.1 alpha...), and I was guessing what you used to create the RFS files inside your LKMod.
I guess parts of the RFS module are in the open source kernels samsung released.
Or you simply fdump them after having modified them?

Thanks for any information you'd like to share! (this forum, for the spica, is the equivalent of xda...)
Happy Easter!
